# OAI field in biblatex/biber

Similarly to DOI, will an OAI (Open Archives Initiative) field be soon added to bibtex/biblatex styles?

I've never seen OAI identifiers used in a reflist, and the OAI identifier standard says "oai-identifiers are not designed for human use, they are designed to be used only with the OAI-PMH" - have you got a sample of their use in a reflist? –  Charles Stewart Nov 5 '10 at 19:38
ok, here is a document with such a reference http://cel.archives-ouvertes.fr/cel-00451733/fr/ See the reference page [last page] and reference Sidoroff. There is an oai reference with an hyperlink to the appropriate webpage. I think we should see more of this kind of link as long as pdf is the norm (which won't last soomuch longer). –  pluton Jan 8 '11 at 18:05

With the help of experts, here is one solution that satisfies oai requirements. The oai references require a repository and a number such as, for instance oai:hal.example.com:hal-0000001 that can be used to reconstruct the actual internet address of the document of interest, here : http://hal.example.com/hal-000001/

the eprint and eprinttype fields together with the following definition shall be used:

\def\oaitourl#1:#2{#1/#2}
\DeclareFieldFormat{eprint:oai}%

\begin{document}
\cite{EX}
\end{document}


together with, in the .bib file :

@TechReport{EX,
author =      {Name, First name},
title =       {Report},
institution = {INH},
year =        {2010},
eprint =      {hal.example.com:hal-000000001},
eprinttype =  {oai}}


The thing is that it would be even better with an oai field directly in the .bib file.

edit: This approach requires the use of the biblatex package together with the biber engine.

I get this error with the command DeclareFieldFormat dl.dropboxusercontent.com/u/62073194/… Do you know why? –  Masi Oct 30 '13 at 11:39
@Masi you have to use biblatex and the associated biber engine in this approach: \usepackage[style=numeric-comp,sorting=nyt, sortcites=true,autopunct=true,babel=hyphen,hyperref=true,backref=true]{biblatex}‌​. From your file, you seem to be using natbib with bibtex I would say. Am I correct? –  pluton Oct 30 '13 at 12:12
Yes, you are correct. –  Masi Oct 30 '13 at 12:14
@Masi please retry with biblatex and biber and let me know if it works. –  pluton Oct 30 '13 at 18:16

I didn't find any reference to OAI in the Feature Tracker of the biblatex page at sourceforge. You should consider to create a feature request.

after reading biblatex guide, I feel that considering a request on the oai field or offering a patch may be appropriate. Other people than just myself may be soon interested in this field. –  pluton Nov 17 '10 at 18:36

biblatex has resources for custom field types. (p. 26 of texdoc biblatex ) It would mean modifying the bibliography style (since none of the standard types make use of, say verba ). So it is already possible to make use of oai fields, with a little work...

-
yes, coming back to lockstep's suggestion and my original post, it may be a the bst-like style level that the oai field could be added. I'll try to investigate. –  pluton Nov 5 '10 at 18:26
